Changing Seas at Cellular to Cross-Ocean Scales. Australia relies greatly upon its rich natural environmental resources for goods, services and for economic growth (tourism, fisheries, and recreational industries). Climate change is one of the biggest threats to the natural marine environment. As the climate warms and oceans become more acidic, corals, the framework builders of reefs, experience unfavourable conditions.

Australia relies greatly upon its rich natural environmental resources for goods, services and for economic growth (tourism, fisheries, and recreational industries). Climate change is one of the biggest threats to the natural marine environment. As the climate warms and oceans become more acidic, corals, the framework builders of reefs, experience unfavourable conditions. This project aims to better understand the processes by which ocean acidification and climate change affect corals, and to develop management tools for the mitigation of, and acclimation to, climate change. By so doing, this project will enable managers of Australia's Great Barrier Reef to better respond to the threatening challenges that climate change poses. Read moreRead less
Understanding mosquito smell system: a new frontier in mosquito control. This project aims to identify and functionally investigate mosquito smell receptors, which are critical in detecting volatile compounds and locating their hosts from a considerable distance away.

This project aims to identify and functionally investigate mosquito smell receptors, which are critical in detecting volatile compounds and locating their hosts from a considerable distance away. Mosquitoes display preferences for certain hosts over others, primarily determined by volatile chemicals produced by hosts. This study builds on recently discovered, novel, host-derived volatile compounds, which can elicit robust responses and attractiveness from mosquitoes. Expected outcomes of the project are enhanced understanding of mosquito smell system and behaviours. This could provide significant benefits to how we can fight mosquitoes and mosquito-transmitted diseases in a more efficient and environmentally responsible way.Read moreRead less
Mass-production of beneficial insects for commercial pest management - physicochemical definition of oviposition sites for development of cost-efficient artificial substrates. The mass-production of beneficial insects for commercial purposes demands the development of cost-effective techniques for breeding and distributing them to growers.

To circumvent this difficulty, it should be possible to defin ....Mass-production of beneficial insects for commercial pest management - physicochemical definition of oviposition sites for development of cost-efficient artificial substrates. The mass-production of beneficial insects for commercial purposes demands the development of cost-effective techniques for breeding and distributing them to growers. Many predatory beneficial insects lay their eggs in sites that prevent effective mass culturing. To circumvent this difficulty, it should be possible to define such oviposition sites in chemical and physical terms, and then use the information to develop artificial substrates that are convenient for mass rearing the insects and for disseminating them to growers. We will use the mealybug predator Cryptolaemus montrouszieri to test the feasibility of this approach and to assess its application to other beneficial species.Read moreRead less

This project seeks to investigate the molecular principles of brain wiring in mammals and how small changes can generate complex outcomes. Neurons in the mammalian brain must be precisely wired together for the brain to function correctly. The project aims to identify the molecular and cellular rules governing commissural wiring in the mammalian cortex to determine how the largest fibre tract in the human brain, the corpus callosum, evolved. This may have involved modifications in mechanisms affecting axon guidance that differ between placentals and marsupials. The project investigates the regulatory gene networks determining commissural neuron fate, the regulation of axon guidance components, and the influence of surrounding brain tissue on the development of commissural connections.Read moreRead less
